Formosan Mountain Dog is originated from Taiwan but Tea Cup Chihuahua is originated from Mexico. Formosan Mountain Dog may grow 14 cm / 6 inches higher than Tea Cup Chihuahua. Formosan Mountain Dog may weigh 15 kg / 34 pounds more than Tea Cup Chihuahua. Both Formosan Mountain Dog and Tea Cup Chihuahua has almost same life span. Formosan Mountain Dog may have more litter size than Tea Cup Chihuahua. Formosan Mountain Dog requires Low Maintenance. But Tea Cup Chihuahua requires Moderate Maintenance
The Formosan Mountain Dog is most often known as the Taiwan dog and it is a landrace indigenous to Taiwan. It is a small to medium breed of dog that was semi-wild at one time. The colonialization of Taiwan and other foreigners help to fully domesticate the Formosan Mountain Dog. They were found to be very trainable and uniquely suited for the terrain around Taiwan. The dogs were easy to train and now serve as hunting dogs, stunt dogs, guard dogs, rescue dogs, therapy dog and personal companions. There are three types of Formosans two smaller types and one medium. However, the original pure Formosan Mountain Dog is getting close to extinction again because the government and people have provided no protection or conservation efforts for them. These dogs have been living in Taiwan in the mountains and were called Formosan Mountain Dogs when Taiwan was known as Formosa. They come from a line of Southeast Asian hunting/gun dogs and they are considered ‘rare’ now.
According to historian Dr. Sung Yung-yi, the breed went through 4 major catastrophes that affected their development. The first of these was the Dutch Establishment in 1624. The Dutch colonized Taiwan and imported both people and dogs. The dog they brought in was called the Flying Dog and was either Greyhound or Pointer. Eventually, the Flying Dog bred with the Formosan Mountain Dog. This along with the slaughter of dogs belonging to the indigenous people by the government, starting the decline of the original Taiwan dog.
In 1895, it was the Japanese acquiring Taiwan following the First Sino-Japanese War. The Japanese bred the Formosan Mountain Dog extensively with the own Japanese dogs. This further diluted the line and authenticity of Taiwan dogs.
This was followed by World War II when German Shepherds traveled with the US Army and they cross-bred with the Formosan. This was the third major dilution of the Formosan Mountain dog line. At the same time, the Japanese government considered the Formosan Mountain Dog a sanitation threat and barbaric. They massacred them in large numbers in the name of sanitation.
The fourth and final dilution took place during the Kuomintang Era beginning in 1945 with the arrival of the Chinese Nationalist Party. They brought with them the culture of eating dogs. During this time the economy of Taiwan took off and business people began to import their own foreign dogs that were high priced purebreds. These dogs bred with the Formosan and other Formosans were just abandoned to die. The ranks of the breed became very thin indeed. Today’s pure Formosan is highly valuable and extremely rare. Because of all the crossbreeding over the centuries, today’s purebred Formosan Mountain Dog is very different from the Taiwan dog of old. Today’s Formosan is loved all over the island and is a companion and watchdog.
Today there is an effort by Taiwanese ecologists to put together a research project that would study and preserve the Formosan in its indigenous form. Dr. Yung-yi led this effort. He located only 46 dogs with a pure pedigree, 21 females and 25 males. They let the Food and Agricultural of the United Nations know and the dogs were labeled close to extinction. Reproducing from the indigenous dogs to purify and increase the breed was the goal. The government was not very supportive.
Today the Royal Air Force is looking at the Formosan Dog to use for military security. They are currently only using German Shepherds and needed another choice. It was decided that the Formosan Mountain Dog had a better sense of smell, dexterity, alertness, and hearing as well as better padding on their paws.
Through these efforts and those of foundation stock breeders and owners, the Formosan Mountain Dog in its indigenous form was brought back. Some call this dog a purebred Formosan while others consider it a new type. Standards were presented to the FCI for registrations as a purebred. This debate continues today
Chihuahua is a state in the country of Mexico. From this state, the dog breed Chihuahua and the “teacup, or toy” chihuahua take their name. Interestingly the Chihuahua Club of America maintains that “teacup” Chihuahuas do not exist and that the size differential is normal for the breed. Chihuahuas or their ancestors have been around a very long time, sadly the exact origins of the Chihuahua are lost into the pages of history, but archaeological clues such as wheeled dog toys, art, and pottery link the Chihuahua to Mexico and to the Techichi dog. The Techichi dog at the time of the Spanish Conquistadors was sold for food (not unlike we sell beef or chicken) and also as a companion dog to death. Cortez even mentioned the Techichi dog in a letter sent back to Spain, describing them as being raised for food and sold in the marketplace.
When a death occurred a dog was chosen as a companion and cremated with the deceased. It was believed that the dog helped the soul of the decedent reach their eternal destination. The Techichi dog from which the modern-day chihuahua likely descended was very plentiful in the central American area that is now the country of Mexico and raised by the ancient Toltecs and later the Aztec people.
Chihuahuas are little dogs and come in a variety of coats, head shapes and even (within the designation small) sizes. The designation “teacup, toy or pocket” while not an official breed name is a useful descriptor, since they are the littlest of an already small breed and these minute pets, as puppies, may fit into a teacup or a pocket.
Fortunately while no longer a food source, the chihuahua is now sought after as a loyal and lively pet and companion.
The Formosan Mountain Dog that was seen during Dr. Sung Yung-yi’s research is a medium-sized dog, athletic and fit. It has a deep chest and a slim waist. The ears are half-covered, the nose is black and there is a coating of black on the tongue. This black tongue is the most distinguishing attribute of the Formosan Mountain Dog. The breed has a strong jaw, the skull that is just slightly longer than the muzzle, which is flat and tapered, triangle face and almond eyes. They have a thick coat and upright, curved tail.
The dogs are known to be extremely agile with an ability to hop that is rare in dogs but helps when hunting animals like rats. The Formosan Mountain Dogs hunted in packs with each dog attacking the prey with one bite until it was too exhausted to fight them off any longer.
Chihuahuas are small. Even the bigger ones are only about six pounds and a “teacup” or “toy” is often three pounds or less. Their bodies are slightly longer than they are tall, but even the tallest are not over nine inches. Chihuahua standing under five inches in height is not uncommon in the “teacup” or smallest of these dogs. They have two different head types and a domed skull. One type of head shape is like a deer while the other is described as an apple-shaped head. The apple-shaped heads are more popular than the deer shaped heads, although sometimes in the “teacup” especially the soft spot fails to close at maturity when growth is complete and the bones should knit, therefore leaving a soft spot in their skull – this is called a molera.
Like different shaped heads chihuahua may have long hair or short-haired coats. The short-haired coats are smooth. The Chihuahua coats may be a large variety of colors ranging from black to white, with red, brown, fawn, cream and chocolate and they may be solid-colored, spotted or sabled. Personal preference is the determining factor on the type of coat a pet Chihuahua has since the breed does not have a preferred color, pattern, hair length or feel. Their muzzle (nose/mouth combination) is short and pointed. Chihuahua have have naturally erect pointed ears and large round eyes. A Chihuahuas tail is relatively long and mostly either curled up and over the back or carried up.
The Formosan Mountain Dog is very child-friendly. He is affectionate and loyal to his family and protective of his children.
He is intelligent and has exceptional hunting skills. He is a good guard dog due to his alertness, but they can be fear-aggressive.
He is very adaptable to living in any location as long as there is somewhere for him to get adequate exercise. He is friendly to people and animals.
He is intelligent and learns quickly.
Children friendliness very interactive with family but has been known to nip at small children and bark, so no not really
3. Adaptability yes but they are better off in apartments and homes not out in the country where their size makes them targets for predators.
4. Learning ability average ability to learn but Chihuahua can be but stubborn which may impact ability and willingness to learn.
Because there have not been any studies done on the health of the Formosan Mountain Dog, there is not a lot known about any inherent or genetic health issues. It would seem that some bloodlines are healthy, and others have some serious issues. Especially because there are no studies, it is important for breeders to test for eye issues and skeletal issues through the Orthopedic Foundation for Animals and the Canine Eye Registration Foundation.
Chihuahuas live on average fourteen to eighteen years. There are some issues that may cause concern or lower life expectancy.]
• Hypoglycemia (low blood sugar) is something to watch for. Low blood sugar can cause death in just a few hours but when caught is very easily treated. Some of the symptoms are being uncoordinated when walking, acting sleepy or lethargic, unfocused sight, fainting, having a seizure or having spasms in the muscles of the neck. First aid can right this condition with a sweet supplement like corn syrup, or honey. This is more common in puppies, but the teacup chihuahuas are susceptible.
• Hydrocephalus (water on the brain) can affect many toy dog breeds. The puppy or dog will appear to have an oversized head, and be slow (display lethargy) and grow slower than its littermates.
• Pulmonic stenosis (a heart condition) occurs when the right ventricle is impeded. Teacup Chihuahuas are also susceptible to heart murmurs.
• Collapsed trachea this occurs when the cartilaginous rings in a Chihuahua do not form completely or weaken. This can be hereditary or an acquired condition and occurs in other small breeds of dog.
• Molera – where after finishing growth a soft spot remains in the skull and the bones do not knit. As a puppy, the owner must remain vigilant about head injuries.
• Obesity (overweight). Most of the time this is a result of the Teacup Chihuahua being overfed. Obesity can contribute to a shortened lifespan and chronic bronchitis.
• Cold susceptibility. Cold weather can cause Teacup Chihuahuas to shiver or tremble when exposed and during cold temperatures, the dogs may need to wear a sweater and boots outside and cuddle with their owners under blankets or bask in the sun to stay warm.
• Infected or injured eyes. Due to the prominent eyes, exposure to irritants such as dust, allergens, or dry air can cause the dog to develop this beginning with watering eyes.
Feed a high-quality puppy food for medium size dogs at the rate of a ¼ cup twice a day until 8 months then ½ to ¾ twice a day until 12-16 months.
1 to 2 cups of high-quality dry food split into 2 meals per day.
Generally healthy breed. Keep clean and watch for mites.
This is an energetic breed and he needs a lot of exercise. He must have at least an hour of exercise daily but the more, the better. He loves swimming and jogging with his people. He’s athletic, smart and agile. He does well with field trials, tracking, agility, and obedience.
1. Feeding the Puppies. Puppies should be fed four times a day. Underfeeding can cause the issues of low blood sugar and overfeeding can result in obesity increasing the risk of other health complications.
2. Feeding the Adult. Adult teacups are also vulnerable to hypoglycemia and obesity. Of course, the low blood sugar will be much more acute than obesity and need prompt care if it occurs. Adult teacups should be fed twice a day.
3. Points for Good Health. The chihuahua generally exhibits more vigor and endurance than pet owners expect from such a small breed of dog.
4. Games and Exercise for Teacup Chihuahua. Go ahead and run and play but remember even with the unexpected stamina and endurance this is a very small dog, small legs, using discernment, judgment, and restraint so the games and exercise is fun and builds health and is a special bonding time, without jeopardizing the sugar levels or causing exhaustion or misery.
